Definitions
- This invention concerns the purification of crude aqueous alkanesulfonic acid containing oxidizable impurities. More particularly, it relates to the use of chlorine treatment of such crude material to convert the oxidizable impurities to alkanesulfonyl chloride and thereafter hydrolysing the alkanesulfonyl chloride to alkanesulfonic acid.
- alkanesulfonic acid In the manufacture of alkanesulfonic acid by the reaction of an alkyl mercaptan or dialkyl disulfide with chlorine and aqueous hydrochloric acid at elevated temperature, a crude aqueous (20-35 wt. % water) alkanesulfonic acid containing oxidizable impurities is first formed.
- Dialkyl disulfide, alkyl alkane thiosulfonate and alkanesulfonyl chloride are the principal stable intermediates in this process.
- the total of dialkyl disulfide and alkyl alkane thiosulfonate is referred to as oxidizable impurities in the crude aqueous product.
- the crude product may be purified by heat stripping.
- Heat stripping usually steam stripping, removes some of the oxidizable impurities overhead from the crude product but unexceptable levels remain and the bottoms product of the stripper must be further treated, e.g., by reaction with hydrogen peroxide or ozone, to reduce or eliminate the impurities.
- Figure 1 of the drawing is a flow diagram of the preferred form of the process of the invention.
- This invention is a process of preparing purified C1-C8 alkanesulfonic acid from crude aqueous C1-C8 alkanesulfonic acid containing oxidizable impurities, said process comprising treating said crude aqueous alkanesulfonic acid with chlorine in an amount effective to convert oxidizable impurities to the corresponding alkanesulfonyl chloride, and hydrolyzing said alkanesulfonyl chloride to alkanesulfonic acid.
- This invention relates to the use of chlorine to convert the oxidizable impurities in crude aqueous C1-C8 alkanesulfonic acid to alkanesulfonyl chloride and thereafter hydrolyzing the alkanesulfonyl chloride to alkanesulfonic acid thereby providing a purer alkanesulfonic acid product.
- the preparation of the crude aqueous alkanesulfonic acid is usually through the reaction of a C1-C8 alkyl mercaptan or C1-C8 alkyl disulfide and chlorine in the presence of aqueous hydrochloric acid at elevated temperature.
- While the process is applicable to C1-C8 alkanesulfonic acid including for example methane, ethane, propane, butane, propane, hexane, heptane and octanesulfonic acid, it is preferably used in the purification of crude aqueous C1-C4 alkanesulfonic acid and most preferably crude aqueous methanesulfonic acid (MSA) and, hereinafter, the purification of crude aqueous MSA will be used to demonstrate the invention.
- MSA crude aqueous methanesulfonic acid
- the purification process of this invention is used for the treatment of crude aqueous MSA (20-35 weight % H20) prepared by the reaction of methyl mercaptan with chlorine in the presence of aqueous hydrochloric acid at an elevated temperature ranging from about 85 to 115°C, more preferably about 95 to 105°C and typically about 98°C.
- the crude aqueous MSA recovered from this process contains appreciable quantities of stable intermediates including dimethyl disulfide (DMDS), methyl methane thiosulfonate (MMTS) and methanesulfonyl chloride (MSC).
- DMDS dimethyl disulfide
- MMTS methyl methane thiosulfonate
- MSC methanesulfonyl chloride
- the total of the DMDS and MMTS is referred to as oxidizable impurities in the product specifications.
- crude aqueous MSA containing oxidizable impurities is treated with chlorine in an amount sufficient to convert said oxidizable impurities to MSC and the MSC containing aqueous MSA is subjected to sufficient heat to hydrolyze the MSC to MSA.
- the amount of chlorine used will depend on whether the crude MSA is treated with chlorine as a part of a batch process or as a part of a continuous process.
- the crude aqueous MSA is preferably saturated with chlorine while in the continuous process for making and purifying aqueous MSA, small quantities (preferably 0.1% to 0.8% based on the weight of crude aqueous MSA) are injected into the discharge piping of a reactor producing, e.g., from 1000-1500 pounds per hour of crude aqueous MSA.
- the chlorine is preferably sparged into the discharge tubing close to the bottom of the reactor to ensure that any unreacted chlorine will flow into the reactor to be used in the formation of the crude aqueous MSA from mercaptan.
- the crude aqueous MSA is conventionally passed to a steam stripper or the like to remove undesirable contaminates from the crude aqueous MSA. Chlorides, DMDS, MMTS, MSC, MSA, water and non-condensed chlorine are removed overhead, and an aqueous MSA with substantially reduced oxidizable impurities is recovered as a bottoms product.
- MSC which is produced by the conversion of oxidizable impurities with chlorine, is hydrolyzed in the steam stripper to MSA.
- a finishing reactor which subjects the MSC in the crude aqueous MSA to sufficient heat for a sufficient time to convert the MSC to MSA, may be employed.
- the product of the finishing reactor may then be subjected to steam stripping, if desired.
- While the chlorination of the crude aqueous MSA is preferably carried out in the discharge line or piping, as close as possible to the reactor, beneficial purification results may be obtained by sparging chlorine into the crude at any point in the process subsequent to discharge from the reactor so long as the chlorine makes adequate contact with the oxidizable impurities to react therewith to form MSC and the MSC can be hydrolyzed to MSA.
- Line 22 in Figure 1 of the drawing shows an alternative point of injection of chlorine into the aqueous MSA.
- the purified aqueous MSA is further treated to remove substantially all water, for example, by the evaporation procedures of U.S. patents No's. 4,450,047 or 4,938,846.
- Aqueous methanesulfonic acid (30 wt. % H2O) samples containing several hundred ppm of oxidizable impurities were chlorinated in batch operations by saturating the test samples with chlorine and allowing the chlorine to react with the impurities in the sample for from 48 to 72 hours.
- the aqueous MSA was then air stripped to remove excess chlorine.
- the batch chlorination reduced the oxidizable impurity content of the MSA samples to zero.
- reactor 2 with sidearms used for reactant recycling and temperature control was operated at atmospheric pressure and a temperature of 98 o C to react methyl mercaptan entering the reactor at the rate of 475 pounds per hour through line 4 and chlorine entering the reactor at the rate of 2100 pounds per hour through line 6.
- Crude aqueous MSA (at a concentration of 70 weight percent MSA) was discharged at the bottom of reactor 2 through line 12 at the rate of about 2.2 GPM (gallons/minute) while hydrogen chloride vapors were vented at the top of reactor 2 through line 8.
- the crude aqueous MSA discharged through line 12 contained an average amount of oxidizable impurities in excess of 156 ppm.
- chlorine was sparged into the crude through line 10 positioned close to the bottom of reactor 2 at a rate of about 20 standard cubic feet per minute (0.26% based on the weight of the crude aqueous MSA). Thereafter, the chlorine treated crude was pumped to the top of steam stripper 14 which was operated at a top temperature of 118-125°C by injecting super-heated steam (227°C) near the bottom through line 16.
